Stellarium Description

Stellarium is a free open-source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors.

I have downloaded it several days before on your site. While I have not made clear about how to use it fully! I can not understand many of its functions! I hope you can give me some suggestions or directions on the using of it.

Everything- over 1.6 million stars and general information on all of them! Not only that, it also shows the position of all celestial objects- not only from any point from the Earth, but also from other planets/satellites.
